JONATHAN HALEY, OF RAVENNA, OHIO, ASSIGNOR TO THE EUREKA PATENT GLASS MOLD COMPANY, OF SAME PLACE.

EPECIPICATION forming part of Letters Patent No. 328,482, dated October 20, 1885.

Application filed July 28, 1884. Serial No. 138,928.

valve, which, by its weight on the bottom of the glass article when the mold is turned over, loosens the glass from the mold and enables it to be removed therefrom. This valve is not absolutely essential, though advantageous when the glass has a smooth plain surface 3 but when it is ornamented with figures, and the sides are required to be nearly vertical, it is difficult if not impossible to release the pressed shade from the mold without the valve herein described or its equivalent.

In the drawings, forming a part of this specification, Figure 1 represents a figured shade of pressed glass, and Fig. 2 is a section of the same. The figures may be of birds, flowers, and vines, or any other ornamental device. Fig. 3 is a vertical section of the mold for pressing the glass shade.

The body of the mold s is provided with the top ring, 8, and formed with a recess, 1, in its bottom to receive valve 0. It is supported on the bottom plate, f, which is formed with a slot, f, to receive lever e.

Plunger a may be attached to a press in the ordinary way.

Sliding plug bis formed with a slot, 1), to receive lever e, by means of which plug b is (No model.)

held up with its upper end extending into the mold-cavity sufficiently to permit the molten glass to be placed around it.

WVhen plunger a is being forced down into the mold, its bot-tom impinges on the top of sliding plug 12 before the glass is pressed. In pressing the lass the plunger forces down the plug. When the glass has been pressed, plunger a is withdrawn, and also plug 1), by means of its lever c, and then the body sis turned over by means of its handles h. In this position the weight of ring-valve c, resting on the bottom of the pressedglass shade, loosens it from the mold. Valve 0 loosely surrounds and slides on plug b in recess 3. While body .9 is being turned over valve 0 is held in place by means of bolts 0 in the bottom of body 8, and on which valve 0 slides.

I claim as my invention- 1. In a mold for making pressed glassware, a sliding ring-valve attached to and forming a part of the body of the mold and closing the bottom of the mold-cavity, in combination with and surrounding a sliding plug extending up into the mold-cavity, and a plunger which impinges on the plug before and while pressing the glass, substantially as described.

2. In a mold for making pressed glassware, the body 8, formed with recess 1', in combination with sliding ring-valve 0, attached to body 8, bolts a, sliding plug 12, and plunger a, substantially as described.
